Member Function Documentation
◆ assumed_unit_prefix() [1/2]
| def qtwidgets.scientific_spinbox.ScienDSpinBox.assumed_unit_prefix | ( | self | ) |
This property can fix a default unit prefix that is used for text input.
- Returns
- : None or prefix string
◆ assumed_unit_prefix() [2/2]
| def qtwidgets.scientific_spinbox.ScienDSpinBox.assumed_unit_prefix | ( | self, | |
| unit_prefix | |||
| ) |
This property can fix a default unit prefix that is used for text input.
- Parameters
-
unit_prefix None or unit prefix in the dictionary
◆ setPrefix()
| def qtwidgets.scientific_spinbox.ScienDSpinBox.setPrefix | ( | self, | |
| prefix | |||
| ) |
Set a string to be shown as non-editable prefix in the spinbox.
- Parameters
-
prefix str, the prefix string to be set
◆ setProperty()
| def qtwidgets.scientific_spinbox.ScienDSpinBox.setProperty | ( | self, | |
| prop, | |||
| val | |||
| ) |
For compatibility with QtDesigner.
Somehow the value gets initialized through this method.
- Parameters
-
prop val
◆ setSingleStep()
| def qtwidgets.scientific_spinbox.ScienDSpinBox.setSingleStep | ( | self, | |
| step, | |||
dynamic_stepping = True |
|||
| ) |
Method to set the stepping behaviour of the spinbox (e.g.
when moving the mouse wheel).
When dynamic_stepping=True the spinbox will perform logarithmic steps according to the
values' current order of magnitude. The step parameter is then referring to the step size
relative to the values order of magnitude. Meaning step=0.1 would step increment the second
most significant digit by one etc.
When dynamic_stepping=False the step parameter specifies an absolute step size. Meaning each
time a step is performed this value is added/substracted from the current value.
For maximum roboustness and consistency it is strongly recommended to pass step as Decimal
or string in order to be converted lossless to Decimal.
@param step: Decimal|str, the (relative) step size to set
@param dynamic_stepping: bool, flag indicating the use of dynamic stepping (True) or
constant stepping (False)
◆ validate()
| def qtwidgets.scientific_spinbox.ScienDSpinBox.validate | ( | self, | |
| text, | |||
| position | |||
| ) |
Access method to the validator.
See FloatValidator class for more information.
@param text: str, string to be validated.
@param position: int, current text cursor position
@return: (enum QValidator::State) the returned validator state,
(str) the input string, (int) the cursor position
◆ value()
| def qtwidgets.scientific_spinbox.ScienDSpinBox.value | ( | self | ) |
Getter method to obtain the current value as float.
- Returns
- : float, the current value of the SpinBox
◆ valueFromText()
| def qtwidgets.scientific_spinbox.ScienDSpinBox.valueFromText | ( | self, | |
| text, | |||
use_assumed_unit_prefix = False |
|||
| ) |
This method is responsible for converting a string displayed in the SpinBox into a Decimal.
The input string is already stripped of prefix and suffix. Just the si-prefix may be present.
- Parameters
-
text str, the display string to be converted into a numeric value. This string must be conform with the validator.
- Returns
- : Decimal, the numeric value converted from the input string.
